Monitor or HDTV for College Dorm

I am going to be starting college in august and was originally planning on using my 32" Samsung HDTV as a tv/computer monitor in my dorm room but am now thinking about leaving that home and getting a new, smaller monitor or tv. The main reasons that I am wanting to leave my tv home is that i think it will be a bit overkill in my dorm and I will be home on the weekends and will need a tv. I am looking at getting something along the lines of 25"-27" with LED backlighting. I plan on using HDMI for my macbook(mini dp to HDMI) & ps3, I will also need something with an rf port for the cable in my room. Can anyone give me any suggestions? I would like to stay below $400 as much as possible.
